ELECTROM ECHANICAL GONG.

SPECIFICATION forming part of Letters Patent No. 616,879, dated January 3, 1899.

l Application filed May 14:, 1896. Serial No. 591,577. (No model.)

To all whom t may concern.-

Beit known that I, CLARENCE E. BEACH, residing at Binghamton,in the county of Broome and State of New York, have invented a new and useful Electromechanical Gong, of which the following is a specification.

My invention relates to improvements in electromechanical gon gs in which a normallyrestrained power may be released by the action of an electromagnet, and thus cause a body of suitable material to be projected against a bell or equivalent device; and the objects of my invention are to provide a device which will be more positive in action, more durable, and less liable to get out of adjustment on account of fewer delicate parts than similar apparatus for the purpose now on the market and to render it simple and cheap. A

W'ith these and other objects in view my invention consists of certain peculiar features of construction and arrangement of parts, all of which will now be fully described andfinally embraced in the claims.

In the drawings accompanying and forming a part of this specification, in which like numerals of reference denote the same parts throughout the several views, Figure 1 is a front elevation of the complete apparatus. Fig. 2 is a side elevation of same. Fig. 3 is a perspective View of the armature 27 and arm 30. Fig. 4 is an enlarged front elevation of the ledges 28 and 32, with lever 2O rendered transparent.

In constructing my invention l provide a suitable system of gearing, which maybe actuated by a spring. or weight, as in ordinary clock-movement construction,or any common means may be employed for imparting motion to said gearing. When arranged to be operated by a spring, as shown in Figs. 1 and 2, the spring 1 may be arranged to drive the .wheel 2 in a common manner, or said spring may be secured directly to the shaft 3, thusavoiding the use of the wheel 2 and pinion 4, provision then being made in any common manner for winding the spring 1 without revolving the escapement 5 and gear 9. The pinion 4 and escapement 5 may be mounted upon the shaft 3 in such a manner as to revolve therewith, said pinion receiving its motion from the wheel 2. The internal gear 6 and lever 7 are so mounted upon the shaft 3 as to be capable of rotating independently of said shaft. The pinion 8 is so secured to the lever 7 as to be constantly in engagement with the internal gear 6 and may loe capable of revolving upon its own axis. The gear 9 is so mounted upon the shaft 3 as to revolve therewith and is placed at such a point with relation to the pinion S as to be constantly in engagement with said pinion, or in cases where the spring 1 is attached directly to the shaft 3 said gear 9 and the escapement 5 may be fixed to a sleeve, said sleeve being mounted upon the shaft 3 and arranged to revolve independently of said shaft. Said sleeve would also be provided with a pawl lor dog, which would rest upon the face of a ratchet, which would be placed on the shaft 3 in a common manner.

`A proper number of teeth or stops 10 are provided and may be arranged to project from the face of the internal gear 6 and are so arranged with relation to the motion of the lever 7, as determined by the ratio between the gear 9 and the internal gear 6 in their iniiuence upon said lever, as to be in suitable ratio with the number of teeth contained upon the escapement 5. A pawl 11 is so mounted as to be capable of attaining an oscillating motion and is so situated that it may assume a position where its free end will lie within the path of the teeth 10 and that it may assume another position where it cannot engage with said teeth.

The elastic arm 12 may be supplied for the purpose of relieving the teeth l0 and pawl 11 .from the force of the collision when the motion of the internal gear 6 is interrupted by the action of said pawl, or the pawl 11 may contain an elastic bushing 13 for the same purpose, and though my device will operate without the use of said elastic devices or either of them the use of one or both will materially lessen the wear upon the various moving parts of said device. The spring 14 is so attached to the pawl 11 that its free end may rest against the screw 15, contained in the post 1G, said screwbeing provided for the IOO purpose of adjusting the tension of said spring in such direction as would tend to keep the pawl l1 within the path of the teeth 10. The ledge 17 is provided upon the lever 7 and is so situated as to bring the pawl ll out of the path of the teeth 10 when said lever is in a certain position.

The hammer 1S is secured to the end of the lever 7 and is so placed relatively to the gong 19 or other suitable device as to be adapted to the production of audible signals, or said hammer may be placed on a separate arm, which would receive its motion from the movement of the lever 7.

The lever 20 is suitably supported upon a post 2l in such a manner as to be capable of attaining an oscillating motion. The projection 22, forming part of said lever, is so situated with reference to escapement 5 as to be capable of interrupting the revolution of said escapement whenever the lever is in a certain position, and when said lever is in another position said projection will not be within the path of the escapement 5. The projection 23 may also form part of said lever 2O and is arranged to engage with the pin 24, provided upon the lever 7, and thereby bring and retain the lever 20 in such position as will place the projection 22 within the path of the teeth of the escapement 5. The projection 23 and pin 24E may be omitted. The relation between the projection 22 and teeth upon the escapement should then be such that the action of the teeth against the projection will tend to force said projection out of the path of the teeth, a spring or weight being provided for maintaining the projection in the path of the teeth upon the escapement 5 except at such times as it may have been forced aside by them. The triangular pin 25 (shown in Fig. 4) may be inserted in the end of said lever 20, or the end of the lever itself may be brought to an angle with said lever to form said pin.

The magnets 26 and the armature'27 are supplied, provision being made whereby the amount of space between said magnets and armature may be regulated, and said armature is so supported upon suitable bearings as to be capable of attaining an oscillating motion. The projecting ledge 28 (shown particularly in Fig. 4.-) is provided upon the armature 27 and is so situated in relation to the triangular pin 25, provided upon the lever 20, as to be capable of restraining the oscillation of said lever when the armature is in a certain position. A spring 29 of suiiicient tension is provided for the purpose of withdrawing the armature from the magnets whenever it is not being inliuenced thereby. The arm 30 is so situated that it is normally held in contact with the armature 27 bythe spring 31, and said arm is provided with the projecting ledge 32, which may be brought within the path of the triangular pin 25 whenever the ledge 2S is not within the path of said pin, or the ledge 32 may be contained upon and form part of the armature 27, thus avoiding the use of the arm 30 and spring 3l; but in cases where gongs are arranged to ring continuously while the circuit remains open or closed, as the case may be, the arm 30, ledge 32, and spring 3l should be omitted.

As shown in Fig. 4, the ledges 28 and are so situated with relation to each other and the triangular pin 25 as to be capable of successively restraining the motion of the lever 20, and by means of an inclination of certain faces of the triangular pin 25 or the ledges contained upon the armature 27 and the arm 30, or all of them, provision may be made whereby said ledges will only interrupt the oscillation 'of said lever when said oscillation is in a certain direction; but when the oscillation is in the other direction either the inclination of the faces of the pin 25 or that of the ledges 28 and 32, or all of them, will cause the one of said ledges which may be within the path of the movement of said pin to be so displaced as to permit said pin to pass it.

The lightning-arrester 33, of common construction, may also form part of the device.

It is obvious that various modifications of arrangement, additions, and omissions of parts may be made in the construction of my device without departing from the spirit of my invention, and the striking mechanism shown could be used with any common releasing device, or the releasing device shown would successfully operate with any common form of striking mechanism.

The operation of my device is as follows: When the mainspring l has been wound and a source for the production of electrical energy has been connected to the electromagnets 2G, thereby energizing said magnets, and the lever 7 is maintained in the position shown in Fig. l by its Weight, which tends to revolve the internal gear 6, which is restrained by thepawl ll being in engagement with one of the teeth or stops 10, one of the teeth of the escapement 5 will be brought into engagement with the projection 22, and if arranged to strike but one blow to each complete electrical impulse as soon as the magnets 26 were energized, as hereinbefore provided, the armature 27 forced the arm 30 into such position as to bring the projecting ledge 32 out of engagement with the triangular pin 25, said armature 27 thus assuming such position as to bring the ledge 28 within the path of said pin 25, thus allowing the lever 2O to fall slightly, but not to a sufficient extent to bring the projection 22 out of engagement with said escapement.v Should the flow of current through the magnets 2G be now interrupted, the spring 29 would bring the armature 27 to a position that would release the pin 25 from engagement with the ledge 2S, thus permitting the lever 2O to take such position as will bring the projection 22 out of engagement with the escapement 5, when said escapement and the parts connected thereto would revolve. However, as soon as IOO IlO

the tooth of said escapement which was in engagement with the projection 22 has moved out of the path of the movement of said projection the lever 2O will be returned again to its normal position by the action of the pin 24 against the projection 23, the pin 25 forcing the ledge 32 aside and passing to the upper side of same. Upon releasing the escapement, as hereinbefore provided for, the shaft 3 would make a portion of a revolution which, by the action of the gear 9 and pinion S, the internal gear 6 being held stationary by the pawl 11, would cause the lever 7 to bring the hammer 18 in contact with the gong 19; but just before said hammer reaches the gong the pawl 11 would be forced out of engagement with the one of the teeth 10 with which it had been engaged up to this time by the action of the ledge 17, and when the hammer 18 strikes the gong 19 another tooth of the escapement 5 would be brought in engagement with the projection 22, thus stopping the revolution of said escapement, the shaft 3, pinion Il, gear 9, and parts revoluble therewith. The escapement 5 and gear 9 in continuing their motion after the pawl 1l has been disengaged from the tooth 10 would cause the internal gear 6 to be revolved sufciently to prevent the pawl 11 from reengaging with the tooth 10 when the ledge 17, provided upon the lever 7, ceases to restrain said pawl. When, however, the pawl 11 is disengaged from one ot the teeth 10, the hammer 18 will have received suicient impetus to cause said hammer to strike the gong 19 with considerable force, when the elastic force ,of the collision will cause said hammer and arm to rebound and return again to their normal positions, thereby moving the internal gear 6 a portion of a revolution, and the ledge 17 will cease to restrain the pawl 11 soon after thehammer 1S leaves contact with the gong 19, and will thus permit said pawl to reassume such position as will arrest the motion of the internal gear and parts revolving therewith. /Vhen the projection 22 interrupted the motion of the escapement 5, as hereinbefore provided for, the projection 23 was in engagement with the pin 24, and when said pin was withdrawn from the path of the ledge the pin 25 was brought in engagement with the ledge 32, thus preventing the lever 20 from assuming such position as would permit another tooth of the escapement 5 to pass the projection 22. When the magnet 26 is again energized, the armature 27 and arm 30 will be so iniuenced as to withdraw the ledge 32 from engagement with the pin 25 and simultaneously bring the ledge 2S within the path of the movement of said pin, when the pin would be immediately brought in engagement with said ledge 2S, as hereinbefore provided. It arranged to oper- .ate continuously while the circuit is open and the various parts are in their normal positions, as hereinbefore provided, the operation would be the same as that hereinbefore described, except that after the projection 22 had interrupted the motion of the escapement 5 in the action of the device as soon as the motion of the lever 7 ldisengages the pin 24 from the ledge 23 the escapement 5 will again be released, and the complete operation of the device will continue for an indeiinite period or until the magnets 26 have been again energized, therebyinterrupting the oscillation of the lever 2O by bringing the ledge 28 within the path of the pin 25.
